This type of injury can cause your brain to swell and press on the oculomotor nerve, making one or both of your pupils dilate, Mackay says. Damage to the oculomotor nerve can also make your eyelid droop or limit your eye movement on the side of the injury Mackay says.īrain injury can be caused by something hitting your head, but you can also have an internal injury from a stroke, a brain tumor, or bleeding in your brain. "Severe head trauma can stretch the nerve and damage its fibers, which can result in a dilated pupil," Mackay says. When this nerve is injured, it can cause many different problems in your eyes. The nerve fibers that control the size of your pupil are within a larger nerve that originates in your brainstem called the oculomotor nerve.

Some common drugs that affect your pupils include:Ĭocaine and crack cocaine can cause your pupils to dilate because your body releases higher levels of endorphins and adrenaline, which stimulate the nerves that control your pupil size. Recreational drugs also affect your nervous system and can cause your pupils to dilate or shrink regardless of the light you're in.

There are many different types of medications that can interfere with the nerves that make your pupils dilate, including:Īntihistamines like diphenhydramine (Benadryl) and loratadine (Claritin) Mackay, MD, Director of Neuro-Ophthalmology at the Indiana University School of Medicine. "Certain medications can interfere with the messages from the nerves that tell the pupil to dilate or constrict," says Devin D. Muscles in the colored part of your eye, your iris, then work to constrict or dilate your pupils, letting in more or less light as needed. Pupil size is controlled by the brain, which receives signals from each retina and sends a message for your eyes to adjust to the light. To do this, they react to the amount of light around you - brighter light makes your pupils grow smaller, while low light makes your pupils grow larger. Your pupils help you see by controlling how much light enters your eye. Here are seven reasons your pupils may be dilated, and when you should see a doctor.
